Problem summary tanker general failure analysis and elimination

Antifreeze replacement requirements
Fault phenomenon Cause Analysis Method of exclusion
Can't suck or suck too little
1 Engine speed is too low
2 No oil in the pump
3 suction pipe leak, low vacuum
4 suction pipe plugged
5 Suction pipe in the three-way ball valve is not off
6 The coarse filter is seriously blocked
7 oil pump worn or damaged
8 Intake valve cannot open in vent valve
1 Increase engine speed
2 Refueling
3 block the leak, increase the degree of vacuum
4 Remove plugs
5 Turn the ball valve stem and turn the color point to a stop
6 Cleaning strainer
7 Repair or replace the oil pump
8 Repair vent valve, otherwise easy to suck the tank
No oil from the tank or too little oil
1 Valve is not open or incomplete
2 Freezing water in sedimentation tank
3 Dirty inside the tank, blocking the oil drain
4 vent valve blocked, poor air intake
1 Open the valve
2 Use steam to open the ice and open the sediment to release water
3 Cleaning up dirt
4 repair vent valve
PTO is not working properly
1 Gear wear or excessive gasket between power take-off and gearbox
2 The spacer between the power take-off and the transmission is too thin, the center distance is short, the rotation is difficult, and the gear is easily damaged or the power take-off shell is crushed
3 The power take-up fork is damaged or the cylinder is damaged.
4 Pneumatic valve damage can not control the gas circuit
5 oil seal or gas gasket damage, oil spill
1 Change gear or thin gasket
2 thick gasket
3 Replace fork or repair cylinder, piston
4 repair or replace the pneumatic valve
5 repair or replace the oil seal, gasket
Drive shaft shakes badly
1 Drive shaft bending
2 Poor balance
3 PTO output shaft bearing or oil pump speed increase input shaft bearing wear is serious
4 Gimbal connection bolts loose
5 Front and rear universal joint installation direction is wrong
6 Cardan joint or telescopic spline worn badly
1 Straightening shaft
2 Do a dynamic balance test
3 Replace the corresponding bearing
4 fastening bolts
5 Adjust the orientation of the universal joint
6 Replace the new universal joint or replace the new one directly
Tank or piping system leaking oil
1 There are pores and trachoma in the welding area
2 road mine is not good, the vehicle is bumpy, and there is a tear
Add air pressure to the tank to 36Kpa. Brush soapy water in each part and find the leaking part. After cleaning according to the method described above, repair welding.
Ball valve leakage
Loose end cap bolts
2 Three-way ball valve bottom adjustment seat loose
3 valve body with trachoma or pore
4 "O" ring damage at valve stem
1 Tighten the bolt
2 tighten the adjustment seat
3 Replacement of new ball valve
4 Replace "O" ring
Ventilation valve failure
1 Inlet and exhaust spring failure
2 inlet, exhaust valve stuck
1 Replacement spring
2 Reassemble and remove stuck objects
Flow meter failure
1 Miscellaneous objects stuck in the flowmeter in the elliptical rotor
2 Oval rotor damaged
1 Cleaning debris
2 Replace the rotor

PVC RESIN SG8

In terms of building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, and fibers, PVC was the world`s largest production of general-purpose plastics, and its applications are very widely. Widely used in all aspects

PVC is a white powder with an amorphous structure. The degree of branching is relatively small. The relative density is about 1.4. The glass transition temperature is 77~90°C. It begins to decompose at about 170°C. It has poor stability to light and heat. After prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, causing discoloration, and the physical and mechanical properties also rapidly decline. In actual applications, stabilizers must be added to improve the stability of heat and light.

The production process of PVC Resin SG8 and PVC RESIN SG5 is basically the same, and the production equipment is exactly the same. The main difference lies in the formulation of additives, polymerization temperature, reaction pressure and so on. The reaction temperature and reaction pressure of SG-8 resin have basically reached the working pressure limit of the polymerizer. The reaction requirements are relatively strict, and the requirements on operation, safety, technology, and personnel quality are more stringent, and the resin quality is more difficult to control.
